I vApplicatifulfilled June 27, 1900. Serial No. 21.784. (No model.)

o rit/l whom itmaq/ concern:

le it known that I, LOUIS'D. LAWNIN, a citizen of the United States, residing at Edvmrdsvil le, inthe coun tyol' Madison and State nl illinois, have invented certain new and useful improvements in Urinals, of which the following is a ull, clear, and exact descrip,- tion, reference being' had to the accompanying drawings, 1to1-:ning part of this specification.

The cl-iject of my invention is to provide for an adequate ventilation of the gutter and apartments ot' a urinal and to so form and arrange the parts that they can he easily and readil" assembled or put together.`

.lilly invention consists in features of noveitj-,f hereinafter fully described, and pointed ont in the claims. A

Figure I is a front elevation showing the witter-well in vertical section.l Fig. II is an enlarged detail transverse section taken online ll il, Fig. I. Fig. III is a detail perspective view showing the manner of snpportiilg the 'nach slabs ot the compartments. Fig. IV is a detail perspective view showing one end ci? the gutter.

l represents an elevated tank connected by a pipe 2 in n. drip-pipe 3, from which Water is drained to a gutter e along slightly-inclined back slabs as usual.

C are partition-slabs, which, with the slabs i'orrn the compartments of the. urinal.

7 are the/fioor-slabs between or on which the slabs lsf/rest, the inner ends of the slabs 7 resting onstri ps 8, supported 'a short distance above/tho top ol the gutter on blocks 9 to leahpaces 8 for the passage of air. The blocks il are interposedl between the strips and the lop of the gutter. rIlie'inner ends of 4o the slabs 7 do Anot extend quite to the slabs 6, I there being spaces 10 left between the two for drainage and for thepassage of air.

The slabs 5 are suppoited,asshown in Figs. l and HI, by brackets or hangers ll, bolted or otherwise secured to the lower ends of the slabs C, the hangerscurvingdownwardly, as shown at 12, and their outer ends being turned upwardly, as shown at 3.2i, so that they will receive and hold the slabs 5.

L4 is a weil or recess in which the gutter t is located. The get ter iss uppo'rted on iframes 15," the gutter lhaving -outturned top'ia'nges 16, that restiipon the frames. I have shown a frame at or near each end of the gutter; but more may be used, if desired.

17 represents a Vent-pipe that connects with the well 14, preferably through la number ofbranches 18 and which extend to the outside ol' the building.

By referring:l to Fig. II it .will be seen that 6o there will be a free circulation of air from the gutter through the spaces 8i, thro u gh the well 14., and out through the vent-pipe 18, and likewise thereds a free circulation of air from above the slabs '7 down tiff-rough the spaces. 65

10, through 'the spacessf, through the w'ell 14, and out through the vent-pipe 1S. AThe construction thus provides fora perfectventilation ofthe gutter and the compartments.

20 represents the drain-pipe of the gutter, 7o which is provided with a double trap 21 22,and v. -23 represents an ai r-pipe, forming aco nl muni-v cation between the tank ll and the space be# tween the two traps 2l and 22, so that when air is exhausted from'the space .between the 75 traps through the pipe 23 a siphonic actionY takes place to draw water from the gutter. This arrangement of double trap and air-pipe is well known, and l make no. claim' thereto, per se, as inventor. Y

' 24. is'au overj'lowp'ipe provided with a trap '25 and communicating with the bottom 'of the well M'to'drain ol'f any' water that may enter the w, ll. The -overflowpipe has a vbranclrQt,communicating with the gutter- 85 through' ari/'opening' 27 in the vvthe eddof the'L 'gutter opposite that with which the drain-- pipe connects. l.,

The overflow-pipe 24 sen'ves to receive'alll 'excess of water ov'er thehinonnt requisite to '9o flush the gutter, andsome of such excess or overflow water is constantly maintained in the trap 25 of the overllow-pipe to serve as a seal' against the escape ofv odors to return t0 the gutter. I claim as my invention-'- n .v l. In a' u-rinal, the combination with awell' or recess of a gutter adapted to hold a body .of water and located in saidwell or recess, strips held a distance above the upper. edges loo cl3' the ,gutterto provide.airsp aces, the back slahn, the A{icm-.slabs supported on said strips and arranged to provide air-spaces between them and the back slabs of the urnal, a vent- I pipe communicating with said gutter through said well, a trapped drain-pipe connected to 5 said gutter, and a trapped overow-pipe also connected to-said gutter, substantially as described.-

2. In a urinal, the combination of a gutter adapted to hold a body of water and located xo 'in a well or recess, strips held a distance with said gutter through'saidV Well, and a. trapped drain-'pipe connected to said gutter,

'substantially as and for the purpose set forth.

3. In a urinal, the combina-tion of ya gutter adapted to hold a body of water, a vent-pipe zo communicating with said gutter, a doubletrapped drain-pipe connected Ato said gutter,

and a trapped overow-pipe connectedto said gutter, substantially as set forth.
